      Incomplete posting on my part.
      You would have to actually speak to someone at Quarter Master. The rep I talked to more or less said that. However, no guarantee of success. Because they should make small car clutches, I'd expect them to be able to do something. They might want/need specs from you.

      yeah the 1500 clutch disk is bigger, requires the matching pressure plate and  flywheel with the ring gear swapped over from a 1100/1300.   So you figure you just have so much torque when it hits high rpm that it starts slipping? Thats something.   Would be helpful to know how much torque it takes to make your clutch slip.  I don't know of a spec for it. I know that springs can weaken and of course, there is wear.  One time i didn't have a impact wrench for removing a crank pulley nut.  chocked the wheels and put it in high gear. Didn't get the nut off, but it let me know that the clutch would slip at a little over 100 ft pounds of torque. Seems crazy  that performance clutch sellers will just say "this stage 2 will have a little more hold than stock" and "stage 3 will have a lot more" without quantifying it with some sort of  measurement.  I couldn't find any yugo/fiat clutches on art's link.  I've been eyeing this one for my turbo cabrio project:  http://www.misterclutch.com/1988-yugo-gvx-spec-stage-3-clutch  If I can find an affordable 1500 flywheel, I would go with stage 2 performance clutch for that instead.

      > Our company X1/9 race car uses a aftermarket, new, stock type clutch assy.  It's a respected manufacturer, and has had no problems. The clutch has 10 HARD races on it, 6,500 to 8,500 RPM is the normal engine range, and a few 9,000 RPM runs when shifting point has to be extended. Clutch is for the 1500CC engine, maybe that's what you'll have to do. Don't know if you can redrill the flywheel. The 1500 disc is 7.5 in diameter, the 1100 might be the same as the 1300, 7.145 In. 
      > Go to  http://www.quartermasterusa.com/  I talked to a rep when at the National Championship races in Sept, and you might be wanting a "Rally' type clutch, which has more grip than a street unit. 
      > You can check the Midwest-Bayless site to see what we have. We used a clutch from our parts stock. Can't give you the horse power we have, but our last race, we had more than ever, over a wider RPM range than the prev 9 races.
